Description
The Geissele MK14 Super Modular Rail (SMR) is a compact, free-float AR-15 handguard designed for a slimmer profile and modular accessory mounting. It ships with an updated Geissele barrel nut that provides extended surface contact with the receiver to promote rigidity and straight alignment along the length of the rail. The rail uses Magpul’s M-LOK interface at the 3, 6, and 9 o’clock positions and is finished with a Type III hardcoat anodize in a Desert Tan (DDC) tone. Installation requires a Geissele barrel nut wrench (sold separately).
